Accessors

Entries::const_iterator begin () const
 The first makernote entry.
Entries::const_iterator end () const
 End of the makernote entries.
Entries::const_iterator findIdx (int idx) const
 Find an entry by idx, return a const iterator to the record.
long size () const
 Return the size of the makernote in bytes.
AutoPtr create (bool alloc=true) const
 Return an auto-pointer to an newly created, empty instance of the same type as this. The makernote entries are not copied. The caller owns the new object and the auto-pointer ensures that it will be deleted.
AutoPtr clone () const
 Return an auto-pointer to a clone of this object. The caller owns the new object and the auto-pointer ensures that it will be deleted.
const TagInfotagList ()
 Return read-only list of built-in Canon tags.
const TagInfotagListCs ()
 Return read-only list of built-in Canon Camera Settings tags.
const TagInfotagListSi ()
 Return read-only list of built-in Canon Shot Info tags.
const TagInfotagListPa ()
 Return read-only list of built-in Canon Panorama tags.
const TagInfotagListCf ()
 Return read-only list of built-in Canon Custom Function tags.
const TagInfotagListPi ()
 Return read-only list of built-in Canon Picture Info tags.

Public Types

typedef std::auto_ptr< CanonMakerNoteAutoPtr
 Shortcut for a CanonMakerNote auto pointer.

Public Member Functions

Creators
 CanonMakerNote (bool alloc=true)
 Constructor. Allows to choose whether or not memory management is required for the makernote entries.
 CanonMakerNote (const CanonMakerNote &rhs)
 Copy constructor.
virtual ~CanonMakerNote ()
 Virtual destructor.
Manipulators
int read (const byte *buf, long len, long start, ByteOrder byteOrder, long shift)
 Read the makernote, including the makernote header, from the Exif data buffer.
long copy (byte *buf, ByteOrder byteOrder, long offset)
 Copy (write) the makerNote to the character buffer buf at position offset (from the start of the TIFF header), encoded in byte order byteOrder. Update internal offsets if necessary. Return the number of bytes written.
void add (const Entry &entry)
 Add the entry to the makernote. No duplicate-check is performed, i.e., it is possible to add multiple entries with the same tag. The memory allocation mode of the entry to be added must be the same as that of the makernote and the IFD id of the entry must be set to 'makerIfd'.
Entries::iterator begin ()
 The first makernote entry.
Entries::iterator end ()
 End of the makernote entries.
void updateBase (byte *pNewBase)
 Update the base pointer of the MakerNote and all its entries to pNewBase.

Member Function Documentation

AutoPtr Exiv2::CanonMakerNote::clone  )  const
 

Return an auto-pointer to a clone of this object. The caller owns the new object and the auto-pointer ensures that it will be deleted.

Note:
In non-alloc mode the clone potentially contains pointers to the same data buffer as the original. Use updateBase(byte* pNewBase) to adjust them.

Reimplemented from Exiv2::IfdMakerNote.

AutoPtr Exiv2::CanonMakerNote::create bool  alloc = true  )  const
 

Return an auto-pointer to an newly created, empty instance of the same type as this. The makernote entries are not copied. The caller owns the new object and the auto-pointer ensures that it will be deleted.

Parameters:
alloc Memory management model for the newly created object. Indicates if memory required to store data should be allocated and deallocated (true) or not (false). If false, only pointers to the buffer provided to read() will be kept. See Ifd for more background on this concept.

Reimplemented from Exiv2::IfdMakerNote.

int Exiv2::CanonMakerNote::read const byte buf,
long  len,
long  start,
ByteOrder  byteOrder,
long  shift
[virtual]
 

Read the makernote, including the makernote header, from the Exif data buffer.

Parameters:
buf Pointer to the Exif data buffer that contains the MakerNote to decode. The buffer should contain all Exif data starting from the TIFF header.
len Number of bytes in the Exif data buffer
start MakerNote starts at buf + start.
byteOrder Applicable byte order (little or big endian).
shift IFD offsets are relative to buf + shift.
Returns:
0 if successful.

Reimplemented from Exiv2::IfdMakerNote.

void Exiv2::CanonMakerNote::updateBase byte pNewBase  )  [virtual]
 

Update the base pointer of the MakerNote and all its entries to pNewBase.

Allows to re-locate the underlying data buffer to a new location pNewBase. This method only has an effect in non-alloc mode.

Reimplemented from Exiv2::IfdMakerNote.
